Hi Giannihapsis -
I'm Kevin B., I do apologize for the inconvenience that you're experiencing right now, let me help you sort things out.
The files on the screenshot provided appears to be system files or program data of Sea of Thieves which is installed on your computer via Microsoft Store App.
Are you trying to delete those files on your computer?
If so, deleting them in normal mode might not be possible as windows might be using some of the files in which it will prevent you from removing or modify those files. If you're trying to delete those files, you may try to do it in safemode.
Boot your computer in safemode. Safemode is a windows environment used to troubleshoot, diagnose and repair corrupted windows system files. While computer is in safemode, no 3rd party application will run, not even your anti-virus, and selected services needed by windows to boot are the only running service on the computer. This ensures us that the computer will only use applications and services at a minimal level to avoid 3rd party conflicting application and services.
Please click on the link below and follow the steps in booting your computer in safemode.

Note: removing the data files will render Sea of Thieves unusable on your computer. You may need to reinstall the application back if in case you want to have it installed.
Hope this will help and have a bless day!
Thanks.
Kevin B.
